I recently purchased the Sonos Arc ultra. It doesn't seem to be playing Dolby Atmos. The Sonos app shows Dolby Digital Plus 5.1.
The soundbar is connected to HDMI eArc on Sony Bravia XR55A80K. Sound & Audio output settings are all ok
The content being played on the TV shows 4K Dolby Vision. I've configured Truplay as well.
Same content on my Bose SOUNDBAR SB700 gives good surround effects.
What could be missing? Or is it a bug in Sonos app or firmware
What is the content, and from what app/source are you playing it? Not all Dolby Vision (a video standard) content is Dolby Atmos (an audio standard).
+19Do you have either Apple Music or Amazon Music Unlimited? If so does Dolby Atmos music show as Dolby Atmos on the Now Playing screen?
Thanks Jgatie & MoPac.
The content is Grand Turismo from both Netflix and Sony Pictures Core. On Sony Pictures Core, it clearly shows Dolby Atmos on the TV, but like I said earlier, on the Sonos app it shows Dolby Digital Plus 5.1.
As per your suggestion, tried with Amazon music, and I can see Dolby Atmos in now playing on the Sonos app.
Does this mean it's something to do with how my Sony TV is sending the audio track to the soundbar?

I’d say: Yes. Sonos devices can only play what they receive.
+18Yes, probably. Sonos can only play what is is sent.

What’s sent/what’s received. This is the other way of looking at it 😜
+19In the TV Settings > Display and Sounds make sure eARC Mode is set to Auto.
